Movement of the base is restricted. The restricted mogul base is used for many mercury, metal halide, and sodium lamps. It also used for incandescent lamps over 300 W. Lamps requiring more than 200 V are more likely to have a mogul (or larger) base instead of a medium base.

Used for most mercury, metal halide, sodium lamps, and also incandescent lamps over 300 watts. Lamps requiring more than 200 volts are more likely to have a mogul (or larger) base rather than a medium base.

The medium base is the standard household base for lamps up to about 300 W. Medium bases are also used for a few mercury and sodium lamps under 100 W. The term "skirted" means that the base flares out at the top.

Mogul bases are used for most mercury, metal halide, and sodium lamps. They are also used for incandescent lamps over 300 W. Lamps requiring more than 200 V are more likely to have a mogul (or larger) base instead of a medium base.

Bases are used for most mercury, metal halide, and sodium lamps. They are also used for incandescent lamps over 300 W. Lamps requiring more than 200 V are more likely to have a mogul (or larger) base instead of a medium base. The base has prongs instead of threads.

Used for most mercury, metal halide, sodium lamps, and also incandescent lamps over 300 watts. Lamps requiring more than 200 volts are more likely to have a mogul (or larger) base rather than a medium base. No screw, iPost connection.

Used for most mercury, metal halide, sodium lamps, and also incandescent lamps over 300 watts. Lamps requiring more than 200 volts are more likely to have a mogul (or larger) base rather than a medium base. The base has two prongs as opposed to thread.

Used for most mercury, metal halide, sodium lamps, and also incandescent lamps over 300 watts. Lamps requiring more than 200 volts are more likely to have a mogul (or larger) base rather than a medium base. No screw, end prong connection.

The lamp has a particular orientation determined by the base. The position-oriented mogul base is used for many mercury, metal halide, and sodium lamps. It is also used for incandescent lamps over 300 W. Lamps requiring more than 200 V are more likely to have a mogul (or larger) base instead of a medium base.

The medium base is the standard household base for lamps up to about 300 W. Medium bases are also used for a few mercury and sodium lamps under 100 W. The three-contact medium base has thicker threads than an ordinary medium base.

Mogul bases are used for most mercury, metal halide, and sodium lamps. They are also used for incandescent lamps over 300 W. Lamps requiring more than 200 V are more likely to have a mogul (or larger) base instead of a medium base.
